The forcefully flowing Antietam reminds us that most of our bridges were built at the site of natural fords. They made natural meeting and market places, and soon water-powered mills were built. Increased traffic would soon lead to the need for a bridge, and then a better bridge. The Ford; The Mill; The Bridge: an early industrial triad. It’s a sequence we see all along the Antietam. Roxbury was originally a sawmill, then a grist mill, and finally a distillery! The beautifully restored bridge still serves our road system but alas, the distillery is no more.
